钢框架内填正交胶合木剪力墙结构的性能分析
Analysis of Performance of Steel Frame Filled with Cross-Laminated Timber Shear Walls
摘要: 为了研究用U型阻尼器节点连接的钢框架内填正交胶合木(CLT)剪力墙体系的性能，本文对一榀钢框架内填CLT剪力墙的缩尺构件开展低周反复荷载试验，同时通过OpenSees有限元软件进行模拟分析，结果表明：CLT墙体可同时承受拉压荷载，结构延性和耗能主要通过耗能连接件的变形来实现，抗侧刚度由CLT墙体与钢框架实现，整体倾覆力矩由钢框架承担，框架和CLT剪力墙实现了协同工作，同时也具有良好的延性。采用有限元模型分析得到的试件荷载–位移滞回曲线与试验结果吻合较好。
Abstract: To investigate the performance of steel frames filled with cross-laminated timber (CLT) shear walls connected by U-shaped damping devices, this paper conducted low-cycle reversed loading tests on scaled specimens of steel frames filled with CLT shear walls. Concurrently, simulation analyses were performed using the OpenSees finite element software. The results indicate that CLT walls can withstand both tensile and compressive loads, with structural ductility and energy dissipation primarily achieved through the deformation of energy-dissipating connections. Lateral stiffness is provided by the CLT walls and the steel frame, while overall overturning resistance is borne by the steel frame. The frame and CLT shear walls exhibit synergistic behavior, coupled with good ductility. The load-displacement hysteresis curves obtained from finite element model analyses closely match the experimental results.
